Application iled April 16, 1924. Serial No. 706,949.

This invention relates to pumps, and more particularly pumps especiallydesigned for inflating pneumatic tires.

The primary object of the provide novel means whereby a pump may besecuredto the running board of a motor vehicle and the piston rodthereof connected Y with one o f the driving wheels of the vehicle ofthe power wheels thereof.

so that lthe power of the motor maybe utilized for operating the-pump.

Another object of the invention is toA prof 'i vide novel means forconnecting'the piston rod of the pumpv to the power wheel of the motorvehicle to cause the rotary lmovement of the wheel to be converted into;reciprocat-v ing motion. Y Y v lVith the foregoing .andother objects inviewwhichwill appear as the ydescription proceeds, the invention residesin the combination andV arrangement of part-s and in the details ofconstruction hereinafter described and claimed, it being understood thatchanges in the precise embodimentv of the invention herein disclosed,may be made within the scope of what is claimed, without departing fromthe spirit of the invention.

:Referring to the drawing:

Figure l is an elevational viewdisclosing a pump constructed inaccordance with the invention as supported on the running board of amotor vehicle and connected with one Figure 2 is a sectional vi 2.-'2 ofFigure 1.

Figure 3 is a plan view of the clamping member that clamps the pump tothe running board. y

lFigure 4 is a sectional view through the running board disclosing theclamp inelevation.

ew taken on line Figure 5 is an elevational View showing over which a`liexible tube 23' may be posi-.-

the clamp as secured to a running board.V

Referring to the drawing, in detail, the reference character 5designates the pump cylinder in which the piston 6 operates, the pistonbeing carried on the inner end o f the piston rod 7 so thaty movementofthepiston rod produces a relative movement of the piston 6, toaccomplish the purpose of the invention. f

A head 8 is positioned on one end of the pump cylinder 5 and is providedwith an invention is to .v

opening to'accommodate the shaft l9 formed lntegral with the clampingmember 10 which clampingmember cooperates with the clamp-V ing member l1to clamp the shaft to the running board.

A bolt 412 extends through the clamping i members and secures thevclamping members togetherl in their operative positions. In order thatthev head may be held to the shaft 9, a Cotter pin 13 is provided,andextends through an opening in the shaft 9; i

From the-foregoing it will be obvious that due to this construction,Vthe pump cylinder 'may swing on the shaft 9 to allow the piston rod torotate with the power Wheel.

` v The pistonrod 7 is formed with an opening 14 at one end thereof,which accommodates theshaft 15 formed at one end of the clamping member16, which clamping member isv mounted on the bolt 17. Cooperating withthe clamping member 16 isa member 18 which is of a length toengageadjacent spokes of a `wheel and as shown, the member 18 is provided witha recessed portion to accommodate the head. 19 of the bolt, to preventrotary movementvof the bolt when the nut 20 at the outer' ends ofthe'bolt is being positioned. i l l The'nut V2O also holds'the washer 21into engagement with the piston rod to hold the vehicle may be raised toa position inspaced relation with the ground surface on which thevehicle is standing, whereupon power may be applied to the rear wheelsto reciprocate the piston within its cylinder and accomplish the pumpingoperation.

Extending from the head'8 is a pipe 22 tioned, whichv tube is providedwith the usual'valve nozzle not shown, whereby the tube may be held intoengagement with the valve of a tire to direct air thereto.

' I claim :-l

In a device of the character described, a clamping member comprisingvanl upper sec# tion and a lower section, said upper section having adepending lug, said lower section having an upstanding end formedwith aeov recess to receive 1che lug, said Sections having f inwardly extendedend portions adapted to grip the running board of a vmotor' Avehicle atponts'in Spa-Ced relation with each. other, Y

a. bolt passng't-hougl'l the sections, -to vhold the sections intoclamping relation with' the Vrunning board, and to hold the lug the'support a pump.

In testimony that I orlaln'the foregoing as Ymy own'7 I have hereto axedmy Signature.
